Roller coaster challenge Anna Jensen Cornell environmental inquiry research partnership (CEIRP) program http://ceirp.cornell.edu/default.asp
Roller coaster challenge • students are asked to design and build model roller coasters based on 5 design criteria • thrill • theme • length • safety • cost • presentation/competition
Roller coaster challenge • relates to real world • problem solving • fun • professionalism
Design project • teamwork • using a design rubric • apply what they’ve learned in class • planning • design • construction • presentation skills
Physics • energy • momentum • friction • g forces • centripetal force
Thrill loops hills turns Theme aesthetics creativity Length ride time Safety g forces stay on track Cost construction materials Design criteria
Length Cost Total Alternative Thrill Theme Safety Design rubric Numeric scale - description 1- poor 2-acceptable 3-good
Foam insulation (10/board) glue guns (5/gun) glue sticks (5/package) doweling (0.29/stick) skewers (2/stick) toothpicks (0.5/box)) tubing (0.75/ft) ball bearing/marble (0.35/ball) pipe cleaners (1.50/package) wire (3/spool) construction paper (3/package) vinyl adhesive (3/tube) Materials
Time • Introduction (1) • pose challenge • show materials • design (1-2) • weigh design factors • construction (10-15) • presentation (2-3) • calculations for design
Limiting cost and time • set a height limit • reduce foam board size • limit total cost of design • increase group size (2-4) • use whole tubing
